Use of CR-39 track detector coupled to a boron converter, as thermal neutron detector (exploiting the n,α reaction on 10B), inside Bonner spheres and REM counters.

  • Use of CR-39 track detector coupled to a boron converter, as thermal neutron detector (exploiting the n,α reaction on 10B), inside Bonner spheres and REM counters.

    • The neutron is detected by the 1.47 MeV α particle.




Use the recoil protons (radiator-degrader technique).

  • Use the recoil protons (radiator-degrader technique).

    • The number of tracks is proportional to the fast neutron fluence.
    • The detection efficiency depends on the neutron energy.
  • Calculation of particle LET and impinging angle.









Vt measured from geometrical parameters of tracks formed

  • Vt measured from geometrical parameters of tracks formed

  • LET deduced from V



Work in perspective:

  • Work in perspective:

  • - A full Monte Carlo characterization of the dosimeters - Angular response still to be understood - Metrological characterization for personal and environmental dosimetry - Medical physics application (?) : secondary dose evaluation due to fragments, with LET spectrometry
